BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a firearm, and more particularly to a rail arrangement for a firearm, wherein the rail arrangement provides a plurality of rail surfaces extending longitudinally for the accessory selectively mounting thereat so as to enhance the practical use of the accessory.

2. Description of Related Arts

A conventional firearm generally comprises a firing assembly which includes a barrel and a butt stock extended from a rear end of the firing assembly. For a long gun, such as rifle, the butt stock is adjacent to the shooter's shoulder during firing. Firearm tools or implements, such as an aiming sight for assisting aim by guiding the eye of the shooter to the target, are provided to mount on top of the firing assembly.

Accordingly, the firearm further comprises a mounting rail longitudinally formed a top surface of the firing assembly, wherein the firearm tool is detachably mounted at the mounting rail. For example, the aiming sight is detachably mounted at the mounting rail. The shooter is able to aim the target by aligning the eye to the eyepiece of the aiming sight. However, such configuration of the mounting rail to mount the firearm tool on the firearm has a major drawback.

When the shooter aims the target and shoots, he or she is under an uncover position. In other words, when the eye of the shooter aligns with the eyepiece, a relatively large head portion of the shooter is exposed in a wide-opened manner. However, the shooter should remain out of a line of enemy fire while being able to shoot at the target in an aimed manner. It is impossible to put the shooter at risk in such uncovered position to increase the shooting accuracy via the aiming sight. In other words, in order to fire in a cover position, the shooter may not precisely aim the target through the aiming sight which may reduce the shooting accuracy, waste the ammunition, and even loss his or her life.

In addition, other firearm tools, such as a long-range telescope sight, a short-range telescope sight, a laser sight, a handgrip, a sling adapter, or a flash light, cannot be effectively mounted at the firing assembly at the same time via the mounting rail. In other words, the shooter may merely need to change one firearm tool to another firearm tool for operation.

SUMMARY OF THE PRESENT INVENTION

A main object of the present invention is to provide a rail arrangement for a firearm, wherein the rail arrangement provides a plurality of rail surfaces extending longitudinally for the accessory selectively mounting thereat so as to enhance the practical use of the accessory.

Another object of the present invention is to provide a rail arrangement for a firearm, wherein the rail arrangement comprises two or more angled rails for the firearm accessories detachably and selectively mounting thereto such that the accessory, such as an aiming sight, is slantedly supported on the firearm for the shooter to aim the target so as to minimize the uncover position.

Another object of the present invention is to provide a rail arrangement for a firearm, wherein the shooter is able to selectively mount the firearm accessory, especially for the aiming sight, at one of the angled rails such that both left-hand shooter and right-hand shooter are able to select the position of the aiming sight to shoot from a cover position in an aimed manner.

As shown in FIGS. 2 and 3, the top mounting rail 21 forms on the top mounting side 211 defining two top longitudinal edges 212, wherein each of the angled mounting rails 22, 23 forms at one of the upper slanted mounting sides 221, 231. According to the preferred embodiment, the angled mounting rails 22, 23 are integrally and downwardly extended along the top longitudinal edges 212 of the top mounting rail 21 respectively such that the mounting structure 30 is adapted for detachably holding the accessory at one of the angled mounting rails 22, 23 in a radially inclined manner with respect to the longitudinal axis X of the firearm so as to inclinedly mount the accessory at the upper portion of the firearm at the frame portion 111 thereof. In other words, each of the top longitudinal edges 212 is a common edge between the top mounting rail 21 and the respective angled mounting rail 22, 23.

As shown in FIG. 2, the supporting frame 20 further comprises an upper bracket 201 defining the top mounting rail 21 and the angled mounting rails 22, 23 thereat, and a lower bracket 202 detachably affixing to the upper bracket 201 to form a handguard having a tubular cavity for detachably encircling the frame portion 111 of the firearm.

The lower bracket 201 comprises a bottom mounting rail 24 arranged for longitudinally extending underneath the frame portion 111 of the firearm, and two lower angled mounting rails 25, 26 inclinedly and sidewardly extended from the bottom mounting rail 24 to alignedly engage with the lower angled mounting rails 25, 26 edge-to-edge respectively. In other words, the supporting frame 10 provides six different mounting angles, i.e. the top mounting rail 21, the two angled mounting rails 22, 23 as two upper angled mounting rails, the bottom mounting rail 24, and the two lower angled mounting rails 25, 26, for the user to selectively mount the accessory at the frame portion 111 of the firearm. Therefore, each of the angled mounting sides contains two mounting rails thereat.

The bottom mounting rail 24 forms at the bottom mounting side 241 defining two bottom longitudinal edges 242, wherein the lower angled mounting rails 25, 26 form at the lower slanted mounting sides 241, 251. The lower angled mounting rails 25, 26 are integrally and upwardly extended along the bottom longitudinal edges 242 of the bottom mounting rail 25, 26 respectively, wherein the mounting structures 30 are also provided on the bottom mounting rail 24 and the lower angled mounting rails 25, 26 respectively such that the mounting structure 30 is adapted for detachably holding the accessory at one of the lower angled mounting rails 25, 26 in a radially inclined manner with respect to the longitudinal axis X of the firearm 10 so as to inclinedly mount the accessory at the lower portion of the firearm at the frame portion 111 thereof. In other words, each of the bottom longitudinal edges 242 is a common edge between the bottom mounting rail 24 and the respective angled mounting rail 25, 26.

As shown in FIG. 3, each of the angled mounting rails 22, 23 is downwardly and sidewardly extended from the top mounting rail 21 at 120°. In other words, each of the upper slanted mounting sides 221, 231 is downwardly and sidewardly extended from the top mounting side 211 at 120°. In addition, each of the lower angled mounting rails 25, 26 is upwardly and sidewardly extended from the bottom mounting rail 24 at 120° such that the supporting frame 20 has a hexagonal cross section. Each of the lower slanted mounting sides 251, 261 is upwardly and sidewardly extended from the bottom mounting side 241 at 120°. Therefore, the supporting frame 20 provides six mounting surfaces, i.e. the top mounting surface 211, the two upper slanted mounting surfaces 221, 231, the bottom mounting surface 241, and the two lower slanted mounting surfaces 251, 261, to mount the accessory at the frame portion 111 of the firearm.

It is worth to mention that the six mounting surfaces of the supporting frame 20 provide the optimum configuration for maximizing the number of the accessories mounting thereto because each of the mounting surfaces is wide enough to support the accessory and the inner circumferential size of the supporting frame 20 fits for the frame portion 111 of the firearm.

As shown in FIGS. 1 to 3, the mounting structure 31 comprises a plurality of rail flanges 311 spacedly and integrally provided on the top mounting rail 21, the angled mounting rails 22, 23, the bottom mounting rail 24, and the lower angled mounting rails 25, 26 for detachably engaging with the accessory thereat. According to the preferred embodiment, the rail flanges 311 are integrally protruded from the top mounting surface 211, the two upper slanted mounting surfaces 221, 231, the bottom mounting surface 241, and the two lower slanted mounting surfaces 251, 261 such that the accessory is adapted to detachably mount on one of the mounting surfaces via the rail flanges 311. Accordingly, the rail system 30 can be “Picatinny rail” that each of the rail flanges 311 has a T-shaped cross section.

As shown in FIG. 4, the telescope sight is mounted at one of the angled mounting rails 22, 23 such that the telescope sight is inclinedly and radially mounted at the frame portion 111 of the firearm at the 60°. Therefore, the shooter is able to aim the target through the telescope sight to minimize the uncover position in comparison with the telescope sight being mounted on the top mounting rail 21. In other words, the shooter is able to select the position of the telescope sight with respect to the frame portion 111 of the firearm to maximize the cover position of the shooter.

As shown in FIG. 4, for a right-hand shooter, a long-range telescope sight A is mounted at the top mounting side 211. A short-range telescope sight B is mounted at the upper slanted mounting side 221 with respect to the left side of the frame portion 111 of the firearm to maximize the cover position of the shooter. A laser sight C is mounted at another upper slanted mounting side 231 with respect to the right side of the frame portion 111 of the firearm. A handgrip D is mounted at the bottom mounting side 241 for the shooter to hold the firearm in a stable manner. A sling adapter E is mounted at the lower slanted mounting side 251 with respect to the left side of the frame portion 111 of the firearm. A flash light F is mounted at the lower slanted mounting side 261 with respect to the right side of the frame portion 111 of the firearm to minimize the blind shot of the shooter.

It is worth to mention that the shooter is able to control the laser sight C via the handgrip D when a switch G, such as a pressure pad or a pressure switch, is provided at the handgrip D. Accordingly, a connecting cable H is operatively extended from the switch G to the laser sight C such that when the switch G is actuated, the laser sight C is switched on. Regarding to the present invention, when the laser sight C and the handgrip D are respectively mounted at the supporting frame 20, the connecting cable H can be hidden within the interior of the supporting frame 20, as shown in FIG. 4, so as to prevent the connecting cable H from being tangled or pulled accidentally. It is worth to mention that the flash light F can also be coupled with the switch G via the connecting cable H for operation.

Furthermore, the right-hand shooter is able to inclinedly mount the telescope sight at the angled mounting rail 22 with respect to the left side of the frame portion 111 of the firearm while the left-hand shooter is able to inclinedly mount the telescope sight at the angled mounting rail 23 with respect to the right side of the frame portion 111 of the firearm. In other words, the angled mounting rails 22, 23 and the lower angled mounting rails 25, 26 form the universal mounting configuration for both the right-hand and left-hand shooters to selectively mount the telescope sight to the frame portion 111 of the firearm in a cover position during firing.

One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
